Sticking tappets often produce a distinct ticking or tapping noise that can be heard coming from the engine. This sound is usually more pronounced at idle and may become louder or more irregular during acceleration. The noise is typically due to insufficient lubrication or worn components, leading to a lack of proper clearance between the tappet and the valve. If left unaddressed, this can result in increased engine wear or damage.
